I'm running 33 x 12.5 on stock runner rims. I adjusted to the front torsion bars added low pro bumps up front with new bils and installed a 2" AAL in the rear with new shocks. I have a little rub on the front sway bar, but who needs that thing anyway?
I had the Superlift IFS 4 inch lift and it did great until I SAS. I ran 33s and they lift helped alot compared to stock. Look for one on ebay. I found mine for 530 bucks which came with everything except for tires and those even fit on my stock wheels.
